I don't know, I was just wandering- Níl sé beo looks like níl sé fear.

Wandering all over the neighbourhood, more like!

It doesn't matter what they "look like" - Fear is a noun, so it can't be used in a tá sé ... construction, true enough, you'd need to use is as in is fear é, but beo is an adjective and tá sé beo is a perfectly normal sentence.
